# sound.cpp -> sound.c + sound_glue.cpp.  The orchestration half
# (SOUND_* public ABI, the SOUND_Update 32.32 fixed-point cycle
# loop, the SCSP IBuffer ring, the setjmp recovery point) moves
# to C; the C++ class instances (SS_SCSP SCSP, M68K SoundCPU),
# the eight M68K bus callbacks they need, and scsp.inc stay in
# the new sound_glue.cpp.  The two halves exchange state through
# sound_internal.h: a handful of extern "C" SoundGlue_* wrappers
# around the M68K / SS_SCSP class methods sound.c needs, and four
# extern symbols (SOUND_next_scsp_time, SOUND_jbuf, IBuffer,
# SOUND_IBufferCount) owned by sound.c that the glue side reads /
# writes during the bus-callback and RunSCSP paths.

# scu_dsp_{gen,mvi,jmp,misc}.cpp -> .c.  Phase-5a detemplated the
# four helper functions in scu_dsp_common.inc (DSP_TestCond,
# DSP_InstrPre, DSP_DecodeInstruction, the DSPS::IsRunning member)
# to FORCE_INLINE C-callable forms with const args.  Phase 5b/5c/5d
# monomorphized the four instruction-handler templates:
#   - JMPInstr <looped, cond>            -> 130 named functions
#   - MVIInstr <looped, dest, cond>      -> 2080 named functions
#   - GeneralInstr <l, alu, x, y, d1>    -> 5376 named functions
#   - MiscInstr <looped, op>             -> 8 named functions
# Each scu_dsp_*tab.inc table file regenerated with the new
# underscored names; the hand-dedup pattern in gentab.inc and
# jmptab.inc / mvitab.inc (cond&0x40==0 collapse, alu NOP collapse,
# x_op 0/1 collapse) preserved slot-by-slot so the function-pointer
# tables stay byte-identical pre/post.  DMAInstr stays embedded in
# scu.inc (ss.cpp's TU) since the body still uses BBusRW_DB and
# ABus_Write_DB32 C++ templates from the bus-access layer.
# The STATE_MASK_* enum was hoisted out of `struct DSPS` to file
# scope so the same `STATE_MASK_EXECUTE` spelling compiles in
# both C and C++.

# db.cpp -> db.c. Dead std:: helpers (DB_GetInternalDB,
# DB_GetHHDescriptions, FDIDToString) were removed in an earlier
# commit, leaving only POD tables and lookup functions.
#
# smpc.cpp -> smpc.c. The class-method calls (CPU[X].SetActive,
# CPU[X].SetNMI) and the namespace calls (VDP2::Update, VDP2::Reset,
# VDP2::GetGunXTranslation, VDP2::SetExtLatch) now route through
# extern "C" proxies in ss.cpp and vdp2.cpp respectively.
#
# cdb.cpp -> cdb.c. The BufferCDDA template took a runtime parameter
# (two callsites, both at 75 Hz so cost is unmeasurable).  FileInfoS
# member methods fad()/size() became free FileInfoS_fad/size()
# INLINE helpers.  Five functions with C++ default arguments
# (StartSeek / MakeBaseStatus / MakeReport / CDStatusResults /
# SeekStart2) had ~100 callsites filled in with explicit defaults.
# FilterS::MODE_SEL_X enum hoisted to file scope.  All cdb-internal,
# no public-ABI changes.
#
# vdp2.cpp -> vdp2.c. The `namespace VDP2 { ... }` wrap was lifted
# and the 19 public entry points renamed to VDP2_* (matching the
# extern "C" proxy convention used in earlier commits, which are
# now redundant and removed).  The RW<T,IsWrite> template
# monomorphized into RW_R16 / RW_W8 / RW_W16.  Three auto&
# references converted to __typeof__()* pointers.  Two
# CPU[i].SetExtHaltDMAKludgeFromVDP2 callsites routed through a
# new SH7095_SetExtHaltDMAKludge proxy in ss.cpp.
# vdp2_render.cpp -> vdp2_render.c. Five C++ idioms removed in
# the lead-up to the rename:
#   - TileFetcher<bool> struct template with templated Fetch method
#     replaced by two named POD structs (TileFetcher_Rot,
#     TileFetcher_NonRot) plus 10 free INLINE functions selected
#     by ##-paste dispatch macros (TF_ROT_FETCH, TF_NR_FETCH).
#   - MakeNBGRBGPix<...> templated INLINE function replaced by a
#     do-while macro (MAKE_NBGRBG_PIX) that writes through an
#     output-lvalue arg.
#   - The four `auto&` references in SetupRotVars and the two
#     T_DrawRBG body macros became explicit struct pointers
#     (struct RotVars*, struct TileFetcher_Rot*) with `->`
#     field access.
#   - C++11 `alignas(N)` -> `__attribute__((aligned(N)))` on the
#     LB.lc backing array, the SPSC ring-buffer atomic counters,
#     and the ProducerState / ConsumerState struct decls.
#   - `static constexpr` -> `static const` for the InitOverlay
#     sprite-type LUTs and `#define` for the BurstBuf size / mask
#     scalars used as array bounds.
# Cross-language atomics already brokered via the language-neutral
# vdp2_atomic_u32 + VDP2_ATOMIC_* macros set up in earlier phases.

# The cartridge subsystem, converted from C++ to C. CartInfo was
# already a plain struct of function pointers (C-style polymorphism),
# so the conversion was mechanical -- monomorphizing the small memory-
# access templates and trimming C++-only includes.
# The VDP1 subsystem, converted from C++ to C. The class-with-methods
# rasterizer state (GourauderTheTerrible, VileTex, EdgeStepper) became
# plain structs + free functions; the PlotPixel / DrawLine template
# engine became MDFN_FORCE_INLINE functions taking the former template
# parameters as const args, with per-table thin wrapper functions
# generated by nested macros so each LineFuncTab slot still resolves to
# a distinct, fully constant-folded function -- matching the codegen of
# the original C++ template instantiations.
